Systems and Control Seminar in the Winter Semester 2018/2019

Disturbance Observer Based Control and MPC

Speaker

Time and Place

The seminar talk takes place on November 20, 2018 at 3.30 p.m. in building 7, room 208 at Universitaetsplatz 2.

Abstract

Disturbance Observer Based Control (DOBC) and related methods have been researched and applied in various industrial sectors in the last four decades. This talk gives an overview of a number of widely used linear and nonlinear disturbance/uncertainty estimation techniques, and then discusses and compares various compensation techniques and the procedures of integrating disturbance/uncertainty compensation with a (pre-designed) linear/nonlinear controller. It provides in-depth analysis of the relationships between these methods and, more importantly, on their similarities and differences with a number of well-known control methods. It shows that DOBC and MPC (Model Predictive Control) are naturally complimentary with each other as MPC is able to fully exploit the model information while DOBC copes with unmodelled dynamics and external disturbances.
